Great advice, but most people take advantage of the DeFi hype for quick profit. Therefore, many people are still interested in new projects. Even though they know the huge risk of investing in such a system, people will still do it.
Fast profits can only be obtained by those who invested in the beginning of the Hype DeFi, after that it no longer exists, even for now, there are already some investors who have lost through investing in the DeFi project.
Those who were invested in defi project's in the earlier phase are the ones who have obtained fast profit. But after that, As per the time when defi hype created a huge bubble and due to that many people have did invested money in defi projects and now that bubble got busted and people would start realizing, just because of the greed of fast profits they gonna have lost their money.
